Find threaded and paging

Hi,
I am using cakephp 2.x
I want to paginate some data with tree structure like comments
as I noticed paging is not possible with find threaded because that function fetched all the data and makes it as a tree with other functions
I have tried defining a hasMany property called “children” it works fine but the problem is that you can show only one level replies

is there any other ways?
